The former Dundalk star endured an injury-hit start to life in Scotland

That injury 21 minutes into his debut against Partick Thistle turned out to be more serious than he first thought and kept him out for 14 weeks.

What is more annoying for McMillan is that the injury was not a case of the hamstring giving up after practically two years without a break — it was purely bad luck as he got roughed up.

He told SunSport: “I came on as a sub. I was chasing a through-ball and the keeper came out.

“I got there first and headed it. I actually won a penalty but was punched in the face.

“I got two black eyes and a dead leg — it was just the way I landed. I nearly did the splits and I tore a tendon in my hamstring.

“I’d worked very hard in my time off to make sure I was fit and I wouldn’t get any niggling injuries. If I’d hurt my hamstring because I was sprinting or it was wear and tear or I hadn’t looked after myself, I’d have someone to blame. It was pretty much just a case of bad luck.”
